In the late 1700’s or early 1800’s, Charity Dilse consecrated herself to the Methodist cause for Jesus Christ after hearing a sermon in New Jersey.  After marrying Casper Hendershott in Kentucky they moved to Piqua, Ohio.  In 1807 Methodist Episcopal meetings began at the Hendershott home located near the junction of what is now Broadway and Riverside Drive in Piqua, Ohio and were the first “Religious Group” in Piqua.  This became a Mad River Circuit point.  David Clark was elected “Class Leader” of the Piqua Methodist Society sometime between 1807 and 1815.  In 1815 a log building for meetings was erected in “Upper Piqua”.  A new Building was erected at the corner of Wayne and Green Streets (across from the Flesh Public Library) and then in 1818 a brick building, Greene Street Methodist Episcopal, was erected at the corner of Wayne and Greene Streets.

On May 1, 1853 a team of 89 members established a new congregation at the corner of Wayne and   Miami Streets that was dedicated by Presiding Elder Michael Marley; with Rev. Marfield P. Gladdis and Rev. G.W. Thurber filing the pastoral rolls.  This was know as the Wayne Street Chapel.  On October 2, 1853 The Rev. L.F. VanCleve was appointed as the first regular pastor and in 1868 membership had increased to 200. 

On February 19, 1868 a lot on Water Street was purchased for a new building. The Rev. E.J. Wells was pastor.  (This is approximately where Cassano’s is now located.)  In 1870 the building was erected and dedicated.  The name was then changed to Grace Methodist Episcopal Church with the Rev. A.M. Richards as pastor.

In 1872 this church building was blown down in a strong wind storm and in 1873 another building was erected.  A mortgage was taken out to pay for the rebuilding and the church had difficulty in keeping up the payments.  With missed payments, foreclosure was impending.  A Mr. and Mrs. Himmelright sold their cow to make the payment and thus secured the future of the church. There was a membership of 250 people at that time. 

From 1873-1898 church membership growth was sporadic at best and sometimes regressed. In 1898 membership grew to 334 and then in 1899 membership grew to 450.  While located on Water Street in the early 1900’s under Superintendent G.E. Folk, the Sunday school grew to an enrollment of 703 and church membership to 450.

The “Great Flood” of 1913 did not do very much damage to Grace Church but on December 8, 1913 the Grace Methodist Episcopal Church building was destroyed by fire.  The Dr. Rev. O.L. Utter was the pastor at that time. From 1913-1914 Church services were held in what is now the Masonic Temple (formerly the Baptist Church) while some were held in the auditorium of the YMCA.

On June 24, 1914, there was a ground breaking service for the new building at the corner of Ash and Franklin Streets.  The site was chosen because of the trolley lines that were close by that stopped at this point.  On Sept. 24, 1914 the cornerstone was laid for the building and in May 1915 worship services were held in the Sunday school department of the building until the auditorium was completed.  Dedication services were held for the new building from June 27 through July 2, 1915.  The cost of the building was $41,000.  On Easter of 1924, the new building debt was paid off.

In April of 1953, “Centennial Celebrations” were held with church membership at 730. The Rev. L.J. Rhodeback was the pastor.

In 1965 the ground was broken for the Education Wing. On Nov. 9,1969 the Education Wing was consecrated with Bishop Gerald Ensley presiding.  Rev.  Charles M. Johnson was pastor at the time.  Church attendance was low and had dropped to an average of 154 people on Sunday morning.  Membership was 615. 

In the Spring of 1971 there was a “Lay Witness Mission” where lay members shared about a personal relationship with Jesus Christ and members felt a new beginning in a new and closer walk with Jesus Christ.  Rev. Jack F. Chalk became the pastor in 1977, when membership was at 641 with a weekly attendance of 283.

In 1985, the church hired Lee Strawhun as Youth Pastor.  Under Lee's leadership, a strong student ministry grew and became the central focus of Grace's ministry.  Lee was followed by Chris Cahill, Jon Morgan, Tony Penner, Jon Ferguson, and Bryan Lloyd (current Pastor of Student Ministries).

As attendance grew along with limited parking Grace United Methodist once again began searching for a new location, under the direction of Rev. Wayne Fowler.  The current property was purchased because it is located next to the junior and senior high school, and student ministry is very important at Grace Church.   Ground breaking was held on North County Road 25-A on August 8, 1999 and the first service at the Family of Grace UMC at 9411 North County Road 25-A was in September 2000, with Rev. Scott Ocke presiding.

In 2002, Rev. Dennis Miller was appointed pastor.  Under his leadership, the church grew to a weekly attendance of 500 persons.  

In 2008, Rev. Terry Fisher became the pastor.
